The article describes an example of design optimizing of gas turbine compressor blade row with coupled simulation (coupled gas dynamics and strength) using technology of fluid-structure-interaction simulation by ANSYS tools. Geometry model, gas-dynamic model, finite element model and optimization technology used in work are described in detail. Optimized design parameters obtained showed improvements of 8% in efficiency and 7% in pressure ratio over the baseline compressor without decrease in safety factor.
